UNITED STATES CHARLES FISHER, OF MANITOYVOO, VISGONSIN,

ASSalGliUlt TO THE INTER- NATIONAL STORE SERVICE COMPANY.

STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 314,814, dated March31, 1885.

Application filed December 29, 1884. (No model.)

To all whom it may concern Be it known that I, CHARLES FISHER, ofManitowoc, in the county of Manitowoc and State ofWisconsin, haveinvented certain new and useful Improvements in Store-Service Systems;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to storeservice systems, the object being toprovide an improved receiver of novel construction for use in connectionwith systems employing rolling carriers.

The invention consists in a receiver for storeservice systems adapted tobe automatically raised and lowered by the movement of the carriers.

The invention further consists in the various appliances, hereinafterfully described, when combined with the receiver of a storeservicesystem.

Figure 1 is a side elevation of a portion of the track and guideway of astore-service system with my improved receiver and its operatin gmechanism applied thereto. Fig. 2 illus trates a detail.

A represents the track or strip upon which the carriers travel, and A ashort guard-strip arranged above the track A and secured th ereto byrods a.

B represents the strip or way, to which the guard-stripAissecuredbyconnecting-stripsb.

0 represents the carrier-seat of the receiver, formed on its upper sidewith a beveled stop, a, and secured loosely by a spanning strip, 0, uponthe way B.

D represents a curved spring, which is secured at its lower end by aspanning strip, (1,

loosely upon the way B. This spring D eX- The seat 0 is provided with anupwardlyprojecting eye-rod, F, to which is secured an elastic cord, G,formed with a knot, g.

H represents a springsupport, rigidly secured at its upper end to theinner side of the way B. This support H extends downwardly below theseat 0 when the latter is in the po- 1 sition shown by the full lines ofFig. 1, and is inwardly bent at its lower end to engage the lower edgeof the seat 0, as shown. This spring is also formed with a bracket-likeextension, h, which projects inwardly over the stop 0 of the seat (whenthe latter is raised) in position to be struck by the carrier I afterthe latter has rolled onto the seat.

The inner side of the way B is recessed adjacent to the spring-supportH, to enable the latter, when struck by the carrier, to be forced out ofengagement with the seat 0, as shown 7 in dotted lines, Fig. 1.

J represents a rod pivoted to a bracket, j, projecting from the strip A,adjacent to the way 13. The inner end of the rod J is bent downwardlyand slightly curved, to extend through an opening formed inthe strip A,and is provided at its free end with a short cross-bar, J upon-which issecured an elastic bumper, J

The elastic cord G extends through an opening in the strip A, and alsothrough an opening in the arm J, the knot 9 being below the arm J, andserving to hold said arm in ele vated position when the receiver israised.

L represents an elastic bumper, which serves as a stop to limit theupward movement of the receiver.

The operation of the improvement thus described is as follows: Thecarrier will readily roll from the track A onto the seat 0, and, 0striking the bracket h of the spring-support H, will release thecarriage, which will immediately descend. The descent will release thearm (2 from its engagement with the shoulder E, and said arm will atonce assume the posi- 5 tion shown in the dotted lines of Fig. 1 tosecure the carrier upon the seat. The descent of the seat has thefurther effect of al lowing the guard-arm J to drop into the positionshown by the dotted lines, Fig. 1, to hold back any carrier that wouldotherwise roll oil after the seat has begun its descent. The

elastic cord G (whose upper end, it will be understood, is suitablysecured above the strip A) will draw the seat back to its raisedposition as soon as its load is removed, thus reengaging thespring-support H with the seat 0, and by means of the knot g elevatingthe guard-arm J to allow the waiting carrier to roll onto the seat.

The spring-support D serves as a brake to prevent undue speed in thedescent of the receiver by reason of its frictional contact with the WayB.

I do not limit myself to the use of an elastic cord for raising theseat, as a spiral spring or other elastic suspensory might be employedin lieu thereof; nor do I limit myself to the other details of form andconstruction, but reserve to myself the right to make all such minorchanges and modifications as may p roperly fall within the scope of myinvention.

Having fully described 1nyinvention,whatl claim as new, and desire tosecure by Letters Patent, is-

l. The combination, with the receiver of a store-service system, of aspring-catch for supporting the receiver in raised position, said catchbeing adapted to be struck by the carrier to automatically release thereceiver, substantially as set forth.

2. The combination, with the receiver, of a spring-catch for supportingthe receiver in raised position, and adapted to automatically releasethe receiver by contact with the carrier, and a spring-brake provided atits free end with an arm to support the carrier upon the seat,substantially as set forth.

3. The combination, with the shouldered end of the track-strip, of theseat and its brakespring, whose free end is provided with a guardarm,which engages the shouldered strip, substantially as set forth.

4. The combination, With the receiver-seat and its beveled stop, of thespring-support provided with an inwardly-proj ecting bracket and ashoulder, as described, the combined spring-brake and guard, and theelastic suspensory, substantially as set forth.

5. The combination, with the receiver-seat and its suspensory formedwith a knot or stop, of a pivoted'guardarm adapted to be automaticallyraised and lowered, substantially as set forth.

6. The combination, with the receiver, of a pivoted guard supportedabove the track and adapted to be automatically raised and lowered bythe elevating-cord of the receiver, substantially as set forth.

7. The combination, with the single guide strip or way, recessed asdescribed, of the carrier-seat andits suspensory formed with aknot orstop, and its beveled stop, the spring-support formed with a shoulder toengage the seat, and with a bracket projection adapted to be struck bythe carrier, the curved spring forming a combined brake and guard, andthe pivoted guard-arm adapted to be automatically raised and lowered,and provided with a bumper at its free end, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CHARLES FISHER.
